Q1. Which improvement methodology uses the DMAIC framework?



A. Lean

B. Six Sigma

C. PDSA

D. Total Quality Management



Correct Answer: Six Sigma ✅



Rationale: Six Sigma uses DMAIC (Define, Measure, Analyze, Improve, Control) as its core
methodology for improving existing processes through a structured, data-driven approach. Option A
is incorrect because Lean focuses on waste reduction and flow, not the DMAIC framework. Option C

,is incorrect because PDSA uses rapid, iterative cycles for small tests of change. Option D is incorrect
because Total Quality Management is a broader management philosophy, not a specific
improvement framework. The key concept is that DMAIC provides a rigorous, data-heavy structure
for complex improvement projects.



Q2. Which improvement methodology emphasizes rapid, iterative small tests of change?



A. Six Sigma

B. Lean

C. PDSA

D. FMEA



Correct Answer: PDSA ✅



Rationale: PDSA (Plan-Do-Study-Act) is designed for rapid, iterative cycles where changes
are tested on a small scale before broader implementation. Option A is incorrect because Six Sigma
uses DMAIC for data-heavy projects that typically take weeks to months. Option B is incorrect
because Lean focuses on waste elimination and flow, not rapid iterative testing. Option D is incorrect
because FMEA is a proactive risk assessment tool, not an improvement methodology. The key
concept is that PDSA is suited for frontline, quick-cycle improvement.



Q3. Which tool is used to prospectively identify failures before they occur?



A. Root cause analysis

B. Failure mode and effects analysis

C. Pareto chart

D. Run chart



Correct Answer: Failure mode and effects analysis ✅



Rationale: FMEA is a proactive, team-based tool that identifies potential failure modes and
their effects before a process is implemented or changed. Option A is incorrect because root cause
analysis is retrospective, conducted after an event occurs. Option C is incorrect because a Pareto
chart identifies the vital few causes from existing data. Option D is incorrect because a run chart

,displays data over time to detect variation. The key concept is that FMEA prevents failures, while RCA
investigates failures that already happened.



Q4. Which tool is used to identify the vital few causes of a problem?



A. Fishbone diagram

B. Pareto chart

C. FMEA

D. Flowchart



Correct Answer: Pareto chart ✅



Rationale: A Pareto chart is a bar graph that orders causes by frequency, applying the 80/20
rule to identify the vital few causes that account for most of the problem. Option A is incorrect
because a fishbone diagram organizes potential causes into categories but does not prioritize them.
Option C is incorrect because FMEA is a prospective risk tool, not a prioritization tool for existing
data. Option D is incorrect because a flowchart displays process steps, not cause frequency. The key
concept is that the Pareto chart helps teams focus on the causes that will yield the greatest
improvement.



Q5. Which tool organizes potential causes into categories?



A. Pareto chart

B. Fishbone diagram

C. Control chart

D. Run chart



Correct Answer: Fishbone diagram ✅



Rationale: A fishbone diagram, also called a cause-and-effect diagram, organizes potential
causes of a problem into categories such as people, process, equipment, and environment. Option A
is incorrect because a Pareto chart prioritizes causes by frequency but does not organize them into
categories. Option C is incorrect because a control chart displays process variation over time. Option

, D is incorrect because a run chart displays data over time to detect trends or shifts. The key concept
is that the fishbone diagram helps teams brainstorm and organize possible causes.



Q6. Which lean tool is used to visualize the flow of materials and information?



A. Value stream map

B. Gemba walk

C. 5S

D. Kaizen



Correct Answer: Value stream map ✅



Rationale: A value stream map is a lean tool that visualizes the flow of materials and
information from start to finish, identifying waste and opportunities for improvement. Option B is
incorrect because a Gemba walk involves going to where the work happens to observe directly.
Option C is incorrect because 5S is a workplace organization method. Option D is incorrect because
Kaizen refers to continuous small improvement. The key concept is that value stream mapping
reveals non-value-added steps in a process.



Q7. Which lean concept refers to waste?



A. Muda

B. Takt time

C. Kanban

D. Poka-yoke



Correct Answer: Muda ✅



Rationale: Muda is the Japanese term for waste, referring to any activity that consumes
resources without creating value for the customer. Option B is incorrect because takt time is the rate
at which a product must be completed to meet customer demand. Option C is incorrect because
Kanban is a scheduling system for just-in-time production. Option D is incorrect because Poka-yoke
refers to error-proofing. The key concept is that eliminating Muda is central to lean improvement.
